Abstract

a invenção é um sistema (1) para ajustar a pressão de um gás, compreendendo: primeiro meio de obturador (5) adequado para causar uma queda de pressão no gás, a partir de uma pressão de alimentação para uma pressão de entrega; meios piloto (11) adequados para prover uma pressão piloto que depende da diferença entre a entrega de pressão e uma pressão de assentamento pré-definida; primeiro meio de acionamento (7) adequado para ser operado pela pressão piloto, de modo a reduzir o grau de abertura do primeiro meio de obturador (5) quando a pressão de entrega excede a pressão de assentamento, e vice-versa; o segundo meio de obturador (8) disposto em série com o primeiro meio de obturador (5) e adequado para assumir uma configuração fechada em que a passagem de gás é evitada; segundo meio de acionamento (10) adequado para ser operado pela pressão piloto, a fim de reduzir o grau de abertura do segundo meio de obturador (8), quando a pressão de entrega excede a pressão de assentamento, e vice-versa. os meios de acionamento (7, 10), são configurados de tal forma que, quando o primeiro meio de obturador (5) está aberto, o grau de abertura do segundo meio de obturador (8) causa uma queda de pressão de gás que é menor do que a queda de pressão produzida pelo primeiro meio de obturador (5).The invention is a system (1) for adjusting the pressure of a gas, comprising: first shutter means (5) suitable for causing a pressure drop in the gas from a supply pressure to a delivery pressure; suitable pilot means (11) for providing a pilot pressure that depends on the difference between the pressure delivery and a predefined seating pressure; first drive means (7) suitable to be operated by pilot pressure so as to reduce the degree of opening of the first shutter means (5) when the delivery pressure exceeds the set pressure, and vice versa; the second shutter means (8) arranged in series with the first shutter means (5) and suitable for assuming a closed configuration in which gas passage is prevented; second drive means (10) suitable to be operated by pilot pressure in order to reduce the degree of opening of the second shutter means (8) when the delivery pressure exceeds the seating pressure, and vice versa. the drive means (7, 10) are configured such that when the first shutter means (5) is open, the degree of openness of the second shutter means (8) causes a gas pressure drop that is less than the pressure drop produced by the first shutter means (5).
